Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method, comprising: receiving, using at least one processor, a digital representation of a first biometric for a person; determining, using the at least one processor, that the digital representation of the first biometric is unverified as associated with an identity of the person; receiving, using the at least one processor, a digital representation of a second biometric for the person that corresponds to a different body part than the digital representation of the first biometric; and upon using the at least one processor to determine that the digital representation of the second biometric is verified as associated with the identity of the person, verify the digital representation of the first biometric as associated with the identity of the person.
Biometric authentication systems often face challenges in verifying identities when a single biometric sample is insufficient or unverified. This invention addresses the problem by cross-verifying multiple biometric samples from different body parts to establish identity confidence. The method involves receiving a digital representation of a first biometric (e.g., a fingerprint) for a person, where this biometric is initially unverified. The system then receives a second digital biometric representation from a different body part (e.g., a facial scan or iris scan) that is already verified as associated with the person's identity. By confirming the second biometric, the system verifies the first biometric, linking it to the same identity. This approach enhances security and reliability by leveraging multiple biometric sources, reducing reliance on a single unverified sample. The method ensures that unverified biometrics can be validated through association with trusted biometric data, improving identity verification processes in applications like access control, financial transactions, or secure authentication systems. The system uses at least one processor to perform these steps, ensuring automated and efficient verification.
2. The method of claim 1 , wherein: the digital representation of the first biometric corresponds to an image of at least a portion of a face; and the digital representation of the second biometric corresponds to a fingerprint.
This invention relates to biometric authentication systems that use multiple distinct biometric modalities for enhanced security. The problem addressed is the need for more robust and reliable authentication methods that reduce false positives and improve user verification accuracy. The system captures and processes two different types of biometric data: a facial image and a fingerprint. The facial image represents at least a portion of a user's face, while the fingerprint corresponds to a unique ridge pattern of the user's finger. These biometric inputs are converted into digital representations, which are then analyzed to verify the user's identity. The combination of facial recognition and fingerprint matching provides a multi-factor authentication approach, leveraging the strengths of both modalities to improve security. The system may include preprocessing steps to enhance the quality of the biometric data, such as noise reduction for the facial image or ridge pattern enhancement for the fingerprint. The digital representations are compared against stored templates to determine a match, with the system potentially using machine learning or statistical algorithms to improve accuracy. This dual-biometric approach is particularly useful in applications requiring high-security authentication, such as financial transactions, access control, or identity verification.
3. The method of claim 1 , wherein the at least one processor receives the digital representation of the first biometric from a same electronic device as the digital representation of the second biometric.
4. The method of claim 1 , wherein the digital representation of the first biometric is determined as unverified because the digital representation of the first biometric is previously unassociated with the identity of the person.
5. The method of claim 1 , wherein the digital representation of the first biometric is determined as unverified because the digital representation of the first biometric is previously associated with the identity of the person through receipt of the digital representation of the first biometric from a remote electronic device.
6. The method of claim 1 , further comprising using the digital representation of the first biometric to identify the person after verification.
7. The method of claim 1 , further comprising using the at least one processor to verify that the digital representation of the second biometric is associated with the identity of the person using an identification token.
8. A method, comprising: determining, using at least one processor, that a digital representation of a first biometric provided by a person for identification is unverified as associated with an identity of the person; prompting, using the at least one processor, for a digital representation of a second biometric for the person wherein the digital representation of the first biometric is a different type of biometric than the digital representation of the second biometric; and upon using the at least one processor to verify that the digital representation of the second biometric is associated with the identity of the person, authorize use of the digital representation of the first biometric for the identification.
9. The method of claim 8 , further comprising identifying the person using the digital representation of the first biometric.
The invention relates to biometric authentication systems, specifically methods for identifying individuals using digital representations of biometric data. The problem addressed is the need for secure and efficient person identification in digital environments, particularly where traditional authentication methods may be insufficient or vulnerable to fraud. The method involves capturing a first biometric sample from a person, such as a fingerprint, facial scan, or other unique physiological or behavioral trait. This sample is converted into a digital representation, which is then processed to extract distinguishing features. The digital representation is compared against stored biometric templates in a database to determine a match. If a match is found, the person is identified, enabling access to secure systems, transactions, or services. Additionally, the method includes verifying the identity of the person using the digital representation of the first biometric. This verification step ensures that the biometric data accurately corresponds to the claimed identity, enhancing security. The system may also incorporate multiple biometric samples or additional authentication factors to further reduce the risk of unauthorized access. The invention is particularly useful in applications requiring high-security authentication, such as financial transactions, government services, or access control systems. By leveraging digital biometric representations, the method provides a robust and scalable solution for identity verification.
10. The method of claim 8 , further comprising using the at least one processor to verify that the digital representation of the second biometric is associated with the identity of the person by comparing the digital representation of the second biometric to data derived from an identification token.
11. The method of claim 10 , wherein the identification token includes at least a picture of at least a portion of the person.
12. The method of claim 8 , further comprising using the at least one processor to verify that the digital representation of the second biometric is associated with the identity of the person by comparing the digital representation of the second biometric to data derived from a monitored biometric capture.
13. The method of claim 8 , further comprising using the at least one processor to verify that the digital representation of the second biometric is associated with the identity of the person by comparing the digital representation of the second biometric to a known biometric.
This invention relates to biometric authentication systems, specifically methods for verifying the identity of a person using biometric data. The problem addressed is ensuring the accuracy and security of identity verification in digital systems, particularly when multiple biometric samples are involved. The method involves capturing a first biometric sample from a person, such as a fingerprint, facial scan, or other unique physiological trait, and generating a digital representation of this biometric. This digital representation is then used to authenticate the person's identity. Additionally, a second biometric sample is captured from the same person, and its digital representation is compared to a known biometric associated with the person's identity. This comparison step ensures that the second biometric sample matches the expected biometric data, confirming the person's identity with higher reliability. The system employs at least one processor to perform these operations, including capturing biometric data, generating digital representations, and conducting the verification comparison. The known biometric used for comparison may be stored in a secure database or retrieved from a trusted source. This multi-step verification process enhances security by cross-referencing multiple biometric samples, reducing the risk of fraud or unauthorized access. The method is applicable in various security-sensitive applications, such as access control, financial transactions, and identity verification systems.
14. The method of claim 8 , wherein: the digital representation of the first biometric corresponds to a fingerprint; and the digital representation of the second biometric corresponds to an image of at least a portion of a face.
